Population justification: The species was previously estimated to number fewer than 2,500 individuals because of its apparent scarcity; however, it has recently been shown to be more widespread and probably more common than previously thought, thus it is now estimated to number 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. Further study is required.
Trend justification: Data suggest that in the species's range states forest extent on average decreased by c.13% from 1990 to 2010 (FAO 2010). The population is therefore suspected to have undergone a moderate decline (10-19%) over the last three generations (estimated at 18 years by BirdLife International), owing to habitat loss and other threats.
